--working-directory option doesn't work with xfce4-terminal.wrapper

"xfce4-terminal.wrapper --working-directory=/tmp" does not set the working directory when launching the terminal.

"xfce4-terminal --working-directory=/tmp" works however.

x-terminal-emulator is set to xfce4-terminal.wrapper by default in Xubuntu, so that's broken too:

[9861][rubiojr.napoleon] sudo update-alternatives --config x-terminal-emulator
